Frequent one sushi place that is on the higher end of the price point and has excellent fish. They, however, as l eat a lot of unagi, always charge me extra for the house made eel sauce as l like more. Sauce is not great, so recently l have been BYOS, using mine and no issue. One deli charges if you want more than the normally delivered 1/2 pickle and so on. Any outrageous stories out there, l suspect there will be.
